Sony DSLR-A300 vs Canon G15

Sony DSLR-A300 advantages over Canon G15

• Larger sensor
  APS-C vs 1/1.7 inch
  More sensor area. Bigger is (generally) better.
• Bigger pixels
  ~ 6.12 vs 1.90 microns
  Better low-light and dynamic range (all else equal)
• Tiltable Screen
  Tiltable vs Fixed
  Tilt the screen for shooting flexbility
• Better color depth

  Better color depth

  Color depth refers to the number of unique colors that a sensor can faithfully capture. Cameras with better color depth will demonstrate smoother transitions from one color to the next, and avoid "banding" in areas with subtle shading. (Blue skies are an example of where you might see color banding.)

  More color depth is generally better, but you'll struggle to notice a difference between two cameras with less than 1 bit of difference. Color depth above 22 bits is considered excellent.

• Higher effective ISO

  Higher effective ISO

  Maximum effective ISO is an estimate of the highest sensitivity at which a camera can capture excellent quality photos.

  Cameras with higher effective ISO will be better choices for indoor photography, night shooting, and indoor sports photography, especially if you intend to make large prints.
